Njira yogwirira ntchito amakina opangira mchenga wobiriwiramakamaka zikuphatikizapo masitepe zotsatirazi, pamodzi ndi mchenga akamaumba luso mu njira kuponyera:
1, Kukonzekera Kwamchenga
Gwiritsani ntchito mchenga watsopano kapena wobwezerezedwanso ngati maziko, ndikuwonjezera zomangira (monga dongo, utomoni, ndi zina zotero) ndi mankhwala ochiritsa mosiyanasiyana. Mwachitsanzo, mumchenga wa utomoni, mchenga wokonzedwanso umafunika 1-2% utomoni ndi 55-65% yochiritsa, pomwe mchenga watsopano umafunika 2-3% utomoni.
Onetsetsani momwe mchenga ukuyendera, kuphatikizapo mphamvu (6-8 kg•f), chinyezi (≤25%), ndi dongo (≤1%).
2, Kukonzekera nkhungu
Yang'anani nkhungu (chitsanzo kapena core box) kuti muwone kuphwanyidwa, midadada yosunthika, ndi mapini opeza. Gwiritsani ntchito chotulutsa nkhungu kuti muwonetsetse kuti zikuyenda bwino.
Ikani zida zothandizira monga ma geting system ndi kuzizira, ndikuchotsa dzimbiri kapena zomatira mchenga.
3, Kudzaza Mchenga ndi Kuphatikizika
Thirani mchenga wosakanikirana mu botolo kapena core box, kutaya mtanda woyambirira kuti muwonetsetse kuchira kofanana.
Gwirizanitsani mchenga pamakina kapena pamanja kuti muchotse malo otayirira, kenaka mulingo pamwamba.
4. Kutulutsa mpweya
Gwiritsani ntchito singano zotulutsa mpweya kuti mupange mpweya wolowera mumchenga. Kuya kwa mpweya mu nkhungu chapamwamba kuyenera kukhala 30-40 mm kuchokera pamwamba pa nkhungu, pamene nkhungu yapansi imafunika 50-70 mm kuti zitsulo zosungunuka zisamatayike.
5, Msonkhano wa Mold ndi Kutsanulira
Gwirizanitsani nkhungu zapamwamba ndi zapansi kuti mupange mphuno yathunthu yoponyera.
Thirani chitsulo chosungunula, chomwe chimalimba muzotayira mwaukali pambuyo pa kuzirala.
6, Pambuyo pa Chithandizo
Chotsani mchenga pakuponyera, yeretsani chogwirira ntchito, ndikuchiza kutentha kapena kuyang'ana.
Kayendedwe ka makina opangira mchenga wobiriwira amafanana ndi kuumba kwamanja koma kumapangitsa kuti ntchitoyo ikhale yabwino komanso yosasunthika kudzera pamakina, ndikupangitsa kuti ikhale yoyenera kupanga zambiri. Zofunikira zenizeni (monga kutentha kwa mchenga ndi mlingo wa resin) ziyenera kusinthidwa kutengera momwe zinthu zimapangidwira.
Malingaliro a kampani Quanzhou Juneng Machinery Co.,Ltd. ndi kampani ya Shengda Machinery Co., Ltd. okhazikika pakuponya equipment.A mkulu-chatekinoloje R&D ogwira ntchito amene kalekale chinkhoswe pa chitukuko ndi kupanga zida kuponyera, makina akamaumba basi, ndi kuponyera mizere msonkhano.
